Preparation of LaPO4:Tb green nanophosphor by spray pyrolysis and application as luminescent pearl pigment |
초록 |
The phosphor is a useful material as a security material because it has an advantage of being easily identified using a simple light source. Therefore, if phosphor is used in combination with other security materials, it can be easily identified and the anti-counterfeiting function of the product, secured. Pearl luster pigment is a material that has its own security characteristics because it changes into a specific color depending on the angle of light shining. Therefore, it is possible to manufacture a high-level luminescent security material by introducing a phosphor into the pearlescent pigment. At this point, since the phosphors to be introduced should not impair the characteristics of the pearlescent pigment, optical characteristics and particle sizes corresponding thereto are required. In this study, LaPO4:Tb green nano-phosphors were prepared by using salt-assisted spray pyrolysis(SASP). Also, concentrations of Tb and NaHCO3 were changed to confirm the luminescence characteristics and particle size changes. Finally, phosphors were coated on the surface of pearlescent pigments and results of their luminescent properties were confirmed. |
